Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jesse/openvswitch 

Conflicts:
	net/openvswitch/vport-internal_dev.c

Jesse Gross says:

====================
A couple of minor enhancements for net-next/3.10.  The largest is an
extension to allow variable length metadata to be passed to userspace
with packets.

There is a merge conflict in net/openvswitch/vport-internal_dev.c:
A existing commit modifies internal_dev_mac_addr() and a new commit
deletes it.  The new one is correct, so you can just remove that function.
====================
